CLARENCE M. SYMONDS, OF SAN FRANCISCO, CALIFORNIA.

CANISTER.

SPECIFICATION forming part of Letters Patent No. 311,690, dated February E 1885.

Application filed July 16, 1884.

To all whom it may concern:

Be it known that I, CLARENCE M. SYMoNDs, a citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented an Improved Canister for Teas, Coffees, Spices, 8m; and I do hereby declare that the following description and accompanying drawings are sufficiently full, clear, and exact to enable any person skilled in the art or science to which it most nearly appertains to make and use the same without further invention or experiment.

My invention relates to improvements in that class of canisters having an opening in one corner thereof; and the objects of my invention are, first, to provide a canister in which there is no solder employed or used upon the inside portion of the receptacle; second, to provide a canister having an opening in one corner thereof, with a spring-lid to cover said opening, and which can be easily removed in the operation of filling the canister; third, to provide an improved means for attaching to the end of the canister the spring operating as a clamp to hold the said lid in its closed or raised position; fourth,to provide an improved means for hinging spring-lids to canisters and similar receptacles. These objects I accomplish by means of the construction and arrange ment of the variousparts, as illustrated in the accompanying drawings, in which Figure 1 is a perspective view of my improved canister, showing the lid closed. Fig. 2 is a perspective view of the upper portion of the canister, showing the lid raised up. Fig. 3 is a perspective view of the lid-spring. Fig. l is a perspective view of the clampplate for securing the spring in position. Fig. 5 is a perspective view of the lid. Fig. 6 is a bottom view of a portion of the top end of the can, showing the lid-spring in position. Fig. 7 is a crosssection through the top corner of the can, showing the manner of attaching the side and end plates.

Similar letters of reference are used to indicate like parts throughout the several figures.

In carrying out my invention I first take a rectangular sheet of metal and bend it four times transversely to the direction of its length, so as to form a quadrangular figure or case, A. The opposite ends of the metal plate are (No model.)

brought together upon one of the sides of the quadrangular figure, and are united upon the outer face or side of the case so formed by a strip of solder, a, as shown in Fig. 1. I then take two other pieces of sheet metal and cut them rectangular in plan,and both ofthe same size. One of these plates forms the lower end or bottom, B, of the canister and is held in its proper position by having its outer edges swaged or crimped over the bottom edge of the case A, as clearly shown in Fig. 7, making a perfectly-tight joint. In one corner of the other of the last aforesaid plates, and within the marginal lines thereof, I cut a triangular opening, C, (shown in Fig. 4,) having its apex or right angle at the corner of the plate. Extending outwardly from the base of the opening so formed I cut an oifset or recess,D,which receives the tang of the lid, to be hereinafter described. This last-named opening is made rectangular, and at both ends of the figure I swage up in the plate a short ridge, b, hollow underneath, to receive the side pins or pivotal bearings of thelid. The spring E, which acts in connection with the lid, is formed of a piece of springwire doubled and bent in the form shown in Fig. 3, having its forward or loose end bent upward to form a lip, c, and sides bent inward to form shoulders (1 cl, audits rear ends, 6 e, bent outward. The spring is placed in position on the under surface of the top or head end plate of the canister, with the lipped portion thereof extending upward and outward, and a trifle in advance of the open side of the slot or recess D, as shown in Fig. 6, while the main portion of the spring extends directly backward from the triangular opening C, and is clamped to the end plate by a clamp, F, and rivet, f. This clamp has two grooves, g g, swaged across its face to receive the rounding surface of the spring-wires, which it binds at that portion situated between the shoulders (I and the flared ends 0, and thus end movement of the spring is effectually prevented. The top end, G, of the canister is now swaged or crimped down upon the upper ed es of the case A. It should here be remarked that the triangular opening is out far enough back from the edges of the plate to leave a small ledge (designated by the letter h in Fig. 2) inside of the raised ridge formed by the crimping process, upon which the outer sides or edges of the lid rest when the canister is closed. The lid or cover H is also cut from sheet metal, and triangular in form, of a size somewhat larger than the opening 0, and is provided at its rear side or base with a prong or tang, t, which is crimped around a Wire, forming journal-bearings or pivotal pointsj, which rest within the ridges b. The outer end of the tang is bent downward at right angles and forms a rib, k, which constantly presses down against the spring E, and when the lid is closed the tension or pressure of the spring upon the rib and tang tends to keep the lid in its closed position, and

when the lid is raised up vertical the outer which is forced down until the pintles orjour' nal-bearings j pass beneath the top. plate, when the lid is then moved backward, still maintaining its vertical position, until the said pintles slip upward into the raised ridges b, audit is upon these pivotal points that the lid is moved to raise and lower it. The apex of the lid is provided with an upwardly-bent point or catch, Z, for convenience in raising the same. I

Although this form of construction is shown as applied to a rectangular canister, it is evident that it is equally adapted to cylindrical canisters by making the opening in the end 0 of the canister or can in the form of the segment of a circle, and the lid of corresponding form, with the tang projecting outward from the chord-line of the same.

Having thus described my invention, whatI claim, and desire to secure by Letters Patent, 1s

1. In a canister having a triangular opening in one corner of the head thereof, the reniovable spring-lid H, made triangular in plan, and having a prong or tang, z, and provided with journal-bearings or pintlesj, and a rib, k, substantially as shown, for the purpose set forth.

2. In a canister having a spring-lid to close an opening in the head thereof, the spring E, having upwardcurved lip c, shoulders d, and outward-flared ends 6, in combination with a clamp, F, and rivet f, for securing the spring to the head of the canister, substantially as shown and described.

3. In a canister, the head G of which is provided with a triangular opening, 0, having an offset, D, pintle-recei'ving ridges I), and spring E, secured by a clamp, and having a lip, c, the lid H, having a tang, i, with its outer end bent at an angle to form a rib, is, substantially as shown, for the purpose set forth and specified.

In testimony that I claim the foregoing I have hereunto set my hand and seal.
